I've been looking for the comms between the Helibus and the base in Prestwick, I've just heard a member of the crew contact the base using 419.1375. They are on exercise now. They are for some reason able to contact UK Rescue on HF.

Just had cg999 near us this Evening on the North coast of Northern Ireland. Landed i believe at Coleraine Causeway Hospital. Could only hear them communicate on 128.500 am which is Belfast International airport. Tracked it on FR24 and it seems to be heading back towards Prestwick. Used to hear polycon from where i am but nothing from this one. Irish Rescue 118 would also be active here and i get them on polycon.
